It looks like Kendall Jenner is just being Miley. Kendall attended the Miley Cyrus concert in L.A. this weekend with sisters Khloe and Kourtney Kardashian, and Kendall channeled her inner Mi-Cy with her hair and shocking hand gesture.

On February 22, the three Keeping Up With the Kardashians stars attended Miley's show at the Staples Center, and they posted pics of themselves having a blast.

Khloe posted one pic of herself posing with a giant teddy bear that was wearing a Miley shirt. And she also posted one of Kendall in her seat in the arena with her hair in two buns like Miley wore at the 2013 VMAs. In the photo, Kendall is surreptitiously flipping off the camera with both hands. We saw that, Kendall!

"Bangerzzzz," Khloe captions the shot. And is this really where the girls were sitting? We would have thought that they could have gotten hooked up with closer seats!

Kourtney also posted a photo of herself enjoying champagne at the show with three female friends. "Partay in the USA! #miley," Kourtney captions it.

The venue was packed with celebs, as Christina Aguilera, Katy Perry, Hilary Duff, and Twilight's Kellan Lutz were all in attendance as well. Harry Styles was there, too, but he wasn't photographed with Kendall, and we're hearing that their romance just might be dunzo. Maybe that's what her angst-filled hand gestures are all about?

Are you surprised that all these celebs were at the Miley show? And do you think Kendall's gesture is inappropriate?
